Wonder if Satori will be doing some beating up next chapter now.
That, or collapse attempting to do so. Who can say.
Satori herself is pretty weak. Well, most of her spell cards in SA end up being poor copies of her opponents. Most of all, she's only a stage 4. And, from what we've seen so far of Mizuchi, she doesn't care about spell card rules. That said, Satori is goner if she engages. I bet that she's there because of Yukari's scheme.
Also, was I the only one surprised at Byakuren's 4D chess? That she had that idea of "hey, if something happened to me, let's see who'd react?" and the answer everybody except Kyouko which happened to be the one that would have worried the most but didn't come?
Also Mizuchi trying to escape but only coming back to the entrance? Wait... did Yukari create some kind of sub-Gensokyo only to trap her? Because holy crap.
